Carbuncles are never good. Strength-sapping, painful, ugly, they're to be avoided. Here's the thing, though: while every politician in Washington is cursing the carbuncle, hardly one has complained of the cancer killing the patient. Allowing unlimited, unaccounted-for corporate spending in elections is a malignancy threatening the life of the republic. Permitting Tea Party, left-wing, libertarian, middle-of-the-road -- whatever -- groups to define themselves as untaxed social welfare organizations that may accept unlimited, untaxed, secret corporate gifts and sponsor political ads is a sarcoma on democracy.

Nobody wants the IRS singling out applicants based on politics. The American people do, however, want someone, if not the IRS, someone else, somewhere to do something about the perversion of election finance. The IRS is hardly a good candidate for that job. The Securities and Exchange Commission (SEC) could help. A constitutional amendment would be better.

Over the past decade, an increasing number of political groups sought "social welfare" status instead. That's because of a 2001 law requiring political outfits to disclose their donors. "Social welfare" organizations don't have to do that. Politicized "social welfare" groups sprouted even faster after the U.S. Supreme Court decided in the Citizens United case in 2010 that corporations are people free to spend unlimited cash in elections.

But here's the problem: the tax code requires these groups to work "exclusively" to promote social welfare. Regulations permit some political activity but forbid these groups from functioning primarily for politics.

Another government entity that could help cure the dark money disease is the SEC.

No enforcement there either, though.

Languishing at the SEC is a proposal to require publicly-traded companies to disclose the money they pour into these "social welfare" groups -- funds described as "dark money" because the source is concealed. The idea is that shareholders have a right to know how their investment is used. And it's a popular concept, with more comments filed on this proposal than on any other suggested rule in SEC history -- half a million -- the vast majority in favor.

One method of enforcement is on the move. It is a proposed amendment to the U.S. Constitution that would reverse the Citizens United decision that corporations are people with First Amendment rights to free speech, which includes spending unlimited money on politics. Already, 13 states and more than 300 municipalities have called for approval of the Democracy is For People Amendment. It was introduced in Congress by Independent Vermont Sen. Bernie Sanders and Florida Democratic Rep. Ted Deutch.

It says natural persons who are citizens of the United States may make campaign contributions. Corporations do not fit that definition of human beings, and as a result would be prohibited from making political gifts.

It would allow contributions from Political Action Committees, which are comprised of human beings who get together and donate under the IRS' political committee rules - Section 527. So groups of union members or wealthy CEOs could continue donating.

Move to Amend activists were heartened by a Pennsylvania judge's recent decision that corporations are not people and thus do not have a constitutional right to privacy. Washington County President Judge Debbie O'Dell-Seneca is no Supreme Court justice. But she understands that there's an important distinction in the fact that people can be heartened while corporations can't be. Her decision included this analysis:

"It is axiomatic that corporations, companies and partnership have no "spiritual nature," "feelings," "intellect," "beliefs," "thoughts," "emotions," or "sensations," because they do not exist in the manner that humankind exists. . .They cannot be 'let alone' by government, because businesses are but grapes, ripe upon the vine of the law, that the people of this Commonwealth raise, tend, and prune at their pleasure and need."

To stop toxic corporate interference in elections, the American people could demand that the IRS, which is supposed to be non-partisan, decide exactly what constitutes political activity. They could hope the SEC will do the right thing. What they should do, however, is pass a constitutional amendment clarifying once and for all that corporations are not human and can't usurp the rights of human beings.
